To' all 'whom it may concern.'

Be it known that we, WILBUR W. MARSH and CHARLES H. HACKE'r'r. citizensof the United States o f America, and residents of lWaterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Liners for Centrifugal Liquid-Separators, of which the following is a specification.

Our invention relates to improvements in liners for centrifugal liquid separators, and the object of our improvement is to provide appropriate means whereby a portion of the liquid may be conveyed directly between each adjacent set of separating disks of the liner, thereby equalizing the distribution, and utilizing the whole separating surfaces of the disks. This object we have attained by the means which are hereinafter described and claimed, and which are illustrated in the drawings hereto annexed, in which- Figure l is a vertical section of a liner showing our one piece corrugated distributing device therein, the section being made on the line y y of Fig. 2; Fig. 2 is a plan view of said liner, a portion being sectioned oit on the line :z: a: of Fig. l; Fig. 3 is a vertical section ofa liner, on the line w w oi Fig. 4, showing our separated distributing troughs inserted therein; Fig. 4 is a plan view of the same liner, a portion being sectioned off on the line z z of Fig. 3, and Fig. 5 is a vertical section of a liner, on the line w w oi Fig. 4, the separated distributing troughs being shown as arranged spirally within.

Similar letters refer to similar parts throughout the several views.

The tendency in liners which are formed oi a series of superimposed conical separating devices is for part of these devices or disks to receiveV a larger portion of iuflowing liquid than the others, thereby causing the liquid to be unequally distributed, resulting in a loss of efficiency. We have adopted a distributing device which obviates this defect in liners by conveying an approximately equal portion of the inflowing liquid to the interspace between cach pair of adjacent separating disks. Each separating disk is thus called upon to perform its full share oi the separation, and the liner enabled to act at its full efficiency.

It is our object particularly to convey certain definite portions of the entering liquid to certain specified disks. By doing this, each disk is compelled to perform its own definite share of the separation. If the entering liquid is not thus definitely deflected to certain disks, the first disks encountered by the liquid are caused to do the major part of the separating, leaving the greater number oi the disks ineffective. When a small part of the disks are thus over taxed, the casein in the milk soon clogs up their surfaces. Then the other disks become effective, but as a Whole the bowl loses progressively most of its power to separate the constitutents of the liquid. v

' When we conduct definite portions of the liquid positively to certain disks, the f ull extent of the bowl perpendicularly as Well as radially is used, noclogging by casein results, and the maximum separation occurs. Our improvement thus consists in the limiting of the outwardly sprayed streams, by varying the lengths of the conduits so `as to definitely'locate the issue of the liquid to predetermined disks. v

With this end in view, in a liner composedof separating disks a supported on uprights b attached to an upper plate g and a lower plate h, we have introduced a depending corrugated plate c attached to an upper plate f, plate c being formed With helicallyarranged apertures. The plate f is detachable from the plate y, and also bears an exit tube e for the egress of the lighter constituent ofthe liquid. Said plate c has its corruga tions arranged in a series oi parallel troughs with a single perforation d at the outer angle ot' the lower end of each trough. Each one of the perforatious d is placed opposite to and communicating with one only of the spaces between adjacent pairs of the separating disks b. The liquid is conveyed from without to the distributing troughs and perforations d through the holes 1c in the upper plate f.

Other similar modes of distributing the entering milk or other liquid between the separating disks may be used but their principle is Within the scope of this invention.

In Figs. 3 and 5 We have shown variations in the iorm ofthe distributing device, the principle of distribution being the same.

In Fig. 3 the distributing device is shown in the shape of a number of separated single troughsc each trough being supplied with a plurality of perforations d.

The perforations d may be made of one diameter, but we have shown them of diameters increasing in size from above downward. This progressive increase in the size of the periorations d is thought to be necessary because of the fact that if they were all of the same size the uppermost perforations would receive a larger portion of the iuflowing liquid than the lowermost ones. Enlarging the perforatious therefore tends to approximately equalize the amount of liquid discharged' into the spaces between the disks.

In Fig. 5 we have shown the distributing troughs c as arranged spirally within the interior of the liner.

It is thought that this arrangement tends to aid the flow of liquid and lessen friction.

It will of course be obvious that instead of using a series of distributing troughs each furnished with one or more periorations, that one distributing trough i with the interspaces between ndjacentiseparnting disks lwhereby the inflowlng lng liquid tothe intel-spaces between adjacent separating In -a `liner for centrifugal liquid .separators a serios `jacent separatingdisks', Vsubstantially s described.
